I don't have a problem with the floating ASIs anymore, part of me would have liked a middle ground where a race gained +2 to a single score and then had a couple of +1s to distribute how they wanted, but ultimately I'm fine with the current system, especially now that I've seen some of the playtest material showing that they're getting rid of mountain dwarf which is now one of the least interesting subraces to me to the point where I was thinking of getting rid of the subrace in my games and just using hill dwarf for both of them.The change does make some options flatly superior to others, though.
And I don't have a problem with the floating ASIs. I am an optimizer. I just don't envision anyone grabbing +2 to Intelligence and +1 to Charisma for their cleric for "the role-playing" when they have every reason pick Wisdom and Strength instead for charop. Is the primary incentive for shuffling around ASIs not to have a halfling wizard with 17 Intelligence instead of 15 at first level when the latter is in no way deficient?
